High Keep  

went from 22 to 33 in 15+/- hours on goblins , 6 man group(sometimes 7 =), all untwinked , server 1 week old. Pulling both warrs and raider room up to stairs(at the end of session). Loot is beyond and so is xp. Highest in group got to 35 i think, he wouldnt leave. :P

note: if u want to be able to pull both rooms and stay upstairs, have a nuker who can blast whoever is lightblue/blue to him(mostly upstairs spawns), this will buy u time to keep both rooms in a tidy split. Keep the 2 rooms splitted and consider the rest of the spawns "adds". 1 inc raider is so toast, but 3 is kinda unefficient.

thats how we did it anyway. and for people waiting for room in group, we put them in the room on the right. 2 people actually did 24 and 25 sitting in the room with the 3/4 spawns waiting for spot to open. whenever greenies spawn u train them in there. them be happy , we save time.
